' hereby declare the following to be a full,

clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to'the accompanying drawings, and to figuresof reference marked" thereon, which form a part of this specification.

This invention relates to an improvedwheel that is designed to giveaspring action by means of a construction within the Wheel, and isdesigned to dispense with infiatedtires so that there is no danger ofpuncture, and at the same time to give sufiicient resiliency. to make aneasy riding vehicle.

The invention is designed to provide a Wheel, of this kind, that hasalternate blocks of elastic material and solid blocks placed in betweenthem, the solid blocks having a wedge action on the elastic blocks,these elements being-placed between the felly and a metal dust plate 24,the dust late being preferably secured by means of t 1e bolts 25,

the rim. The blocks abutting also provide a circumferential transmissionthat gives an easy starting to the vehicle, and communicates power fromthe telly to the rim, or vice versa. The elastic bloclisalso provide forthe spring of the wheel, and are therefore subjected to compressions intwo directions, radi'ally and in a circumferential direction.

The invention is illustrated in the accompanying drawing, in whichFigure 1 is a side View of the wheel with the metal dust plate brokenaway to show the spring portion of the wheel in elevation, therimbeingshown in section. section on line 2, 2, in Fig. 1, and Figs. 3 and iarcbottom-views of elastic blocks of different forms.

ll'he wheel consists of any usual style of hub. 10, spokesll and al'elly 12, the telly 12 having,- on its periphery, a band 13 which ispreferably made of steel. Surrounding the felly, and. at a considerabledistance there-' from, so as to provide a space, is a rim l4 which ispreferably of a channel construction,

and is designed to hold any suitable tire l5 which may be of solidrubber, or of any suitai z material. .Dispdsedat suitable. pointsSpeciiication of Letters Patent. Application filed May 25, 1907. serialNo. 375,580.

Fig. 2 1s a Patented June as, race.

in the s ace between the telly and the rim,

.are the locks 15 which are recessed as at 17,

which may be cut straight across as in Fig. '3,

or in heavy constructions where strength is required, the recess can bemade as at 18, in

Fig. 4. This recess receives the head 19 of a bolt 20, and a nut 21, oneach bolt,}serves to secure the bolt and consequently the block ofresilientmaterial, to the telly. The ed es of the block are cut so as tobe radial the hub.

Between each two blocks 16 are solid blocks 22,- these vblocks beingpreferably madeof wood and secured to the rim by the screws 23, althoughother forms of fastening may be employed. The abutting edges of theblocks of solid material, with the blocks of resilient materiahare cuttoform faces in contact, and in this way when weight is supported by thewheel, the block between each two elastic or resilient blocks hasa wedgeac tion tending to ,force the resilient blocks apart, and in this waythe neeessar sprin is secured. This is the case where t e whee is in theosition shown in Fig. 1, but when a resilient lock sustains the weightit is compressed radially.

.We secure to the rim, on each side thereof,

power, and an extremely sensitive Wheel is the result that rides easyover all obstructions and takes up the shock. V Having thus describedour invention,'what we claim is:- I
